Solar/Thermal Home Heating Project Kotzebue Electric Association Community Energy Task Force NANA Economic Development

Rural Vs Urban Energy Costs

June-July 2008 Energy Cost

Kotzebue Elder Winterization Initiative 70 Homes were weatherized by teams using two Kotzebue locals and two Anchorage volunteers VOLUNTEERS:

Kotzebue Solar Fraction of 49.6% From Solar Design Manual for Alaska by Rich Seifert

Flat vs. Evacuated Tube

Ten Elder Homes • Community Energy Task Force to provide volunteer force for installation. • Kotzebue Electric to provide engineering and overall project management. • Elder homes selected based upon agreed upon criteria. • Data acquisition done by CETF, KEA, OTZ Telephone and Alaska Technical Center

Home Seven and Eight • Air Source Heat Pump-Hallowell

Home Nine and Ten • Air Source Heat Pump- Daikin

Conclusion • Final design will be determined after initial planning meetings • The Alaska Technical Center may be used as a initial test site if the air source heat pumps benefit is questionable • The goal is to test equipment for future wide- spread deployment • Manufacturers claims will be verified as to actual cost effectiveness
